Comments. See “Diagnosis” section of L. colemanorum above. The Louisiana specimens loaned by R.E. DeWalt represent a new state record. The Bogue Lusa Creek site, located in Washington Parish, the northeastern most of the Florida Parishes is bordered on the north and east by three Mississippi counties, Pike, Walthall and Pearl River. No Leuctra records are reported for these counties but L. ferruginea is known from several sites in Amite County which borders Pike County.
